Answer:
3. C or 18.
4. Perimeter: 10 Area: 6.25
5. 3 and 16
Step-by-step explanation:
3. Because the area of a triangle is 1/2 the base times the height if you double the area you can divide this total area by one side to find the length of the other side. In this problem that is 72*2 which is 144. Then dividing 144/8 you get 18, which is answer choice C.
4. Since a square has 4 sides that are all the same, you only need to know one side length to know them all. Multiplying one side length (2.5) by itself will get you the are of the square as a whole. Doing this (2.5 multiplied by 2.5 gets the area of 6.25.
For the perimeter calculation use the formula for a perimeter of a square which is one side (2.5) multiplied by 4 is 10, which is the perimeter.
5. This is because 3*16 is 48 or the area of the rectangle.
Answer:
12
Step-by-step explanation:
20 - 5 = 15
15 - 3 = 12
15% of 1950 = 1950 * 0.15 = 292.5
So, sum would be: 1950 + 292.5 = 2242.5
In short, Your Answer would be $2242.5
Hope this helps!
Answer:
The answerers are 90"; 45. 45 and 60, 60, 60.
Step-by-step explanation:
The two sides have the same length this would mean that they have the same angle measure on a triangle the only two answers with two of the same angle measures are 90"; 45. 45 and 60, 60, 60 so therefore they are your answers.
